Please start by watching this video to have a full understanding of what object tracking is, how it works, what all settings mean and best practices to set up object tracking correctly:

See this article to see the easiest and fastest way to create Object trackers.

1. Inlier ratio tracking inititation:
   The inlier ratio tracking initiation setting sets the minimum inlier ratio required before tracking can initiate.
   Setting this value too low, can result in false positive tracking. Setting it too high, might result in not being able to initiate the tracking at all. We recommend using a value between 0.4 and 0.7. Reaching inlier ratio values of 0.7 to 0.8 during the experience, are generally considered as a good result.

2. Inlier ratio tracking minimum: After tracking is initiated, the "inlier ratio tracking minimum" setting becomes relevant, it means that active tracking will stop if the inlier ratio drops below this value.

3. Laplace threshold: The Laplace threshold is an expression in millimeters. A line will be generated whenever the depth jump between surfaces from the camera's point of view, is larger than the defined value.
   A very high value will create a result that primarily shows the contours of your object, as the contours are basically an infinite depth jump.

4. Normal threshold: The normal threshold creates lines determined by changes in the surface direction. A high value will generate lines for hard edges, while a lower value will also generate lines for softer edges. Generally we do not recommend setting this value below 0.1.

5. Key frame distance: The minimum distance between keyframes in mm. The line-model will only be generated for certain keyframes. Therefore a higher value improves the performance at the cost of a lower precision. Lower values cost more performance but increase the precision.

6. Line gradient threshold: Threshold to determine what is considered a contrast line in the video feed. Low values will consider low contrast areas as a candidate, which may result in false positives. High values will only consider very high contrast areas as a candidate, which may result in a lower or too low inlier ratio, so the tracking could fail to initiate. We recommend leaving this setting to the default.

7. Line search length during tracking: This setting determines the orthogonal length around the line model, in which contrast will be searched in the video feed, after tracking initiated.
8. Line search length before tracking: This setting determines the orthogonal length around the line model, in which contrast will be searched in the video feed, before tracking initiates.

When testing these settings, we recommend using debug mode in the app, to validate if the settings you use are the best for your use case.
